Description

Technical Field

[0001] This utility model belongs to the field of stamping backplate technology, and specifically refers to a backplate structure for a large-screen display device. Background Technology

[0002] In the existing technology, the back panels of large-screen display devices such as televisions and computer monitors are mainly produced by stamping. The corresponding holes, slots and other structures can be stamped according to the pre-designed structure to facilitate the installation of other modules and meet some functional requirements of the display device.

[0003] Typically, a metal sheet larger than the product size is used as the base material for stamping. After stamping, burrs inevitably remain at the edges and corners, affecting product quality and appearance. Current practice involves edge banding the back panel, using plastic or other materials to cover the stamped edges to prevent exposure. However, this method complicates the production process, and the plastic or other materials used for edge banding also face challenges such as insufficient strength. Utility Model Content

[0004] The main purpose of this utility model is to provide a back panel structure for a large-screen display device, which solves the problems existing in the prior art, simplifies the production process, and improves product quality.

[0005] To achieve the above objectives, the solution of this utility model is:

[0006] A back panel structure for a large-screen display device includes a back panel body; a mounting slot for mounting a display module is provided in the middle of the back panel body; baffles are provided on all four sides of the back panel body, and the edges of the baffles are provided with flanges. After being folded, the flanges are parallel to the inner wall of the baffles and are clearance-fitted, so that the connection between the flanges and the baffles forms a folded edge with an arc cross section; the mounting slot, baffles, and flanges are all integrally formed by stamping process.

[0007] The backplate body is made of pure metal or alloy materials.

[0008] The side wall of the mounting groove is provided with a step, and the step is provided with a mounting hole for locking the display module of the display device.

[0009] Preferably, the sidewall of the step is provided with a groove.

[0010] A notch is provided at the corner between the flanges of adjacent sides of the back plate body.

[0011] The side wall of the mounting slot is provided with heat dissipation holes.

[0012] Preferably, the heat dissipation holes are arranged at equal intervals along the length or width of the backplate body.

[0013] After adopting the above technical solution, the present invention has the following technical effects:

[0014] This utility model integrates the mounting groove, baffle, and flange into the back panel body using a stamping process. The entire structure is made of metal, ensuring strength and product quality. Meanwhile, the edge of the baffle is formed by stamping and turning inward, so the edge of the metal sheet is no longer exposed but is instead contained within the inner wall of the baffle. This increases the thickness of the baffle to improve strength and also creates a smooth fold at the edge of the baffle, optimizing the product appearance and avoiding exposed burrs.

[0020] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0021] refer to Figure 1-3 As shown, this utility model discloses a back panel structure for a large screen display device, including a back panel body 1; a mounting groove 2 for mounting a display module is provided in the middle of the back panel body 1; baffles 3 are provided on all four sides of the back panel body 1, and flanges 4 are provided on the edges of the baffles 3. After the flanges 4 are folded, they are parallel to the inner wall of the baffles 3 and fit with a gap, so that the connection between the flanges 4 and the baffles 3 forms a folded edge 5 with an arc cross section.

[0022] Mounting groove 2, baffle 3, and flange 4 are all integrally formed by stamping process.

[0023] Through the above solution, this utility model integrates the mounting groove 2, baffle 3, and flange 4 into the back plate body 1 using a stamping process. The entire structure is made of metal, ensuring strength and product quality. At the same time, the edge of the baffle 3 is formed into an inwardly turned flange 4 using a stamping process, so the edge of the metal sheet is no longer exposed but is instead contained within the inner wall of the baffle 3. This not only increases the thickness of the baffle 3 to improve its strength but also forms a smooth folded edge 5 at the edge of the baffle 3, optimizing the product appearance and preventing burrs from being exposed.

[0024] The following are specific embodiments of the present invention.

[0025] The backplate body 1 is made of pure metal or alloy materials, which can ensure the structural strength and hardness of the backplate.

[0026] The side wall of the mounting groove 2 is provided with a step 6, and a mounting hole 7 is provided on the step 6 for locking the display module of the display device, so that the display module does not directly contact the bottom wall of the mounting groove 2, and provides heat dissipation space.

[0027] Furthermore, the side wall of the aforementioned step 6 is provided with a groove 8. The groove 8 makes the connection between the step 6 and the back plate body 1 no longer a flat surface, which can distribute the force, making the structure of the step 6 stronger and less prone to deformation after being subjected to force.

[0028] refer to Figure 3 As shown, a notch 10 is provided at the corner 9 between the flanges 4 of adjacent sides of the backplate body 1. During the stamping process, material will accumulate at the corner, resulting in a thicker thickness at that location and making it difficult to form. By stamping away part of the material at a predetermined position during the stamping process so that a notch 10 can be formed after stamping at that position, the above-mentioned defects can be avoided, making the thickness of the stamped backplate more uniform and improving the yield rate.

[0029] The side wall of the mounting slot 2 is provided with heat dissipation holes 11.

[0030] Furthermore, the aforementioned heat dissipation holes 11 are arranged at equal intervals along the length or width direction of the backplate body 1 to achieve uniform heat dissipation.

[0031] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
